In more detail, when the processing module 105 determines that the at least one parameter measured by the detection module 106 exceeds the threshold, the control signal is immediately generated and transmitted to the power management module 107. When the power management module 107 receives the control signal, it immediately cuts off the supply of power, so that The power output port 108 stops supplying power to the electric device 30, thereby forcibly turning off the operation of the electric device 30, thereby ensuring the safety of the first power line circuit C1 and the electric device 30.
除此之外，電源管理模組107更可輸出複數個不同電壓位準的電壓給電源輸出埠108，以因應不同的內部元件或電器裝置30之電壓需求，換句話說，電源管理模組107不僅可以控制電力的開啟或關閉外，更可以控制電壓的大小。於實務上，電源管理模組107可以為一種繼電器(relay)、固態繼電器(solid state relay，SSR)、閘流器(thyristor)或電源管理積體電路(power management integrated circuit，PMIC)等作為電力與負載之間進行閉合與斷開的控制元件，本發明在此不加以限制。 In addition, the power management module 107 can output a plurality of voltages of different voltage levels to the power output port 108 to respond to voltage requirements of different internal components or electrical devices 30, in other words, the power management module 107. Not only can you control the opening or closing of power, but you can also control the voltage. In practice, the power management module 107 can be a relay, a solid state relay (SSR), a thyristor, or a power management integrated circuit (PMIC). The control element that closes and opens between the load and the load is not limited herein.
儲存模組109透過電力線通訊裝置10a中的電力線通訊模組103以及無線通訊模組104而通訊連接其他的電力線通訊裝置10b~10h，使得儲存模組109可以儲存有其他的電力線通訊裝置10b~10h中的資料訊號以及電力線通訊裝置10a的門檻值與參數資料。於實務上，儲存模組109可以為一種隨機存取記憶體(random access memory，RAM)、唯讀記憶體(read-only memory，ROM)或是快閃記憶體(flash memory)，本發明在此不加以限制。 The storage module 109 communicates with other power line communication devices 10b-10h through the power line communication module 103 and the wireless communication module 104 in the power line communication device 10a, so that the storage module 109 can store other power line communication devices 10b~10h. The data signal in the middle and the threshold value and parameter data of the power line communication device 10a. In practice, the storage module 109 can be a random access memory (RAM), a read-only memory (ROM), or a flash memory. This is not limited.
為了更加清楚說明所述多個電力線通訊裝置10a~10h的資料交換方式，請一併參照圖1A與圖2，電力線通訊裝置10a可以透過電力線通訊模組103而與皆在此相同電力線迴路(即第一電力線迴路C1)中的電力 線通訊裝置10b~10d進行資料訊號的傳輸，並將其資料訊號儲存於自身的儲存模組109中。而於不同電力線迴路(即第二電力線迴路C2)中的電力線通訊裝置10e~10h則可以透過自身的無線通訊模組104來與電力線通訊裝置10a進行資料訊號的傳輸，並將其資料訊號儲存於自身的儲存模組109中。 In order to more clearly explain the data exchange mode of the plurality of power line communication devices 10a to 10h, referring to FIG. 1A and FIG. 2 together, the power line communication device 10a can transmit the same power line circuit through the power line communication module 103 (ie, Power in the first power line loop C1) The line communication devices 10b-10d transmit the data signals and store their data signals in their own storage modules 109. The power line communication devices 10e to 10h in the different power line circuits (ie, the second power line circuit C2) can transmit the data signals to the power line communication device 10a through the wireless communication module 104, and store the data signals thereof. In its own storage module 109.
於實際的操作中，由於主機裝置20通訊連接於所述多個電力線通訊裝置10a~10h的至少其中之一，而所述多個電力線通訊裝置10a~10h又可透過自身的電力線通訊模組103以及無線通訊模組104而互相通訊連接，因此主機裝置20可以透過接收電力線通訊裝置10a~10h所輸出的電力線訊號或無線訊號，據以使主機裝置20可以依據每一個電力線通訊裝置10a~10h中的所述至少一參數而動態地調整每一個電力線通訊裝置10a~10h上的門檻值。 In actual operation, since the host device 20 is communicatively connected to at least one of the plurality of power line communication devices 10a-10h, the plurality of power line communication devices 10a-10h can pass through the power line communication module 103 of the same. And the wireless communication module 104 is connected to each other. Therefore, the host device 20 can receive the power line signal or the wireless signal output by the power line communication devices 10a to 10h, so that the host device 20 can be configured according to each of the power line communication devices 10a to 10h. The at least one parameter dynamically adjusts the threshold value on each of the power line communication devices 10a-10h.
換句話說，每一個電力線通訊裝置10a~10h上的門檻值會依據其耦接的電器裝置30的不同(例如耗電功率的不同或是使用頻率的不同)以及周圍環境的變化而進行適當地修正。舉例來說，當任意一個電力線通訊裝置10a~10h上所耦接的電器裝置30為冰箱時，藉由人工設定或是系統程式自動判斷之方式，主機裝置20會將耦接有冰箱的電力線通訊裝置的門檻值設定為無限大或是無法達到的極大值，使得電源管理模組107永遠持續將此電力線迴路的電力供應至冰箱，以避免發生冰箱因斷電而導致存放於其內的食物產生腐敗之憾事。 In other words, the threshold value of each power line communication device 10a~10h is appropriately changed according to the difference of the electrical device 30 to which it is coupled (for example, the difference in power consumption or the frequency of use) and the change of the surrounding environment. Corrected. For example, when the electrical device 30 coupled to any one of the power line communication devices 10a to 10h is a refrigerator, the host device 20 communicates the power line coupled to the refrigerator by manual setting or automatic judgment by the system program. The threshold value of the device is set to an infinite or unreachable maximum value, so that the power management module 107 always supplies the power of the power line circuit to the refrigerator forever, so as to avoid the occurrence of food stored in the refrigerator due to power failure. The regret of corruption.
以另一例子來說，由於電力線迴路通常是由導電性 能良好的銅所製成，而銅對溫度的電阻率之變化大約以五度為一個刻度，因此當電力線迴路的溫度變化超過五度時，主機裝置20會命令所有的電力線通訊裝置10a~10h對自身的電力線迴路(即第一電力線迴路C1與第二電力線迴路C2)進行電力線訊號的傳輸速率之測試，並將測試完的傳輸速率資料以電力線通訊(如圖1B所示)或無線通訊(如圖1A所示)之方式回傳給主機裝置20，據以使得主機裝置20可以對上述的傳輸速率資料進行運算分析，進而設定出每一個電力線通訊裝置10a~10h於此環境下的門檻值。 As another example, since the power line loop is usually made of conductivity It can be made of good copper, and the change of the resistivity of copper to temperature is about five degrees. Therefore, when the temperature of the power line circuit changes by more than five degrees, the host device 20 will command all the power line communication devices 10a~10h. Test the transmission rate of the power line signal for its own power line loop (ie, the first power line loop C1 and the second power line loop C2), and communicate the tested transmission rate data with power line communication (as shown in FIG. 1B) or wireless communication ( As shown in FIG. 1A, it is transmitted back to the host device 20, so that the host device 20 can perform operation analysis on the above-mentioned transmission rate data, thereby setting the threshold value of each power line communication device 10a~10h in this environment. .
以再一例子來說，由於本發明之電力線通訊裝置10a~10h會不定時地傳送電力線訊號的傳輸速率之資料給主機裝置20，因此當主機裝置20判斷出某一電力線迴路之電力線訊號的傳輸速率產生大幅變化時，主機裝置20會開始檢查使用於此電力線迴路中的電力線通訊裝置之數量是否有所增加或減少，進而設定出於此電力線迴路下的每一個電力線通訊裝置的門檻值。 In another example, since the power line communication devices 10a to 10h of the present invention transmit the data of the transmission rate of the power line signal to the host device 20 from time to time, when the host device 20 determines the transmission of the power line signal of a certain power line circuit. When the rate changes significantly, the host device 20 will begin to check whether the number of power line communication devices used in the power line loop has increased or decreased, thereby setting the threshold for each power line communication device under the power line loop.
承接上述，若於此電力線迴路中再擴增一個電力線通訊裝置，將造成電力線訊號的傳輸速率的下降，此時主機裝置20會控制此電力線迴路中的所有電力線通訊裝置進行電力線訊號的傳輸速率的互相測試，並利用上述的測試結果設定出每一個電力線通訊裝置的門檻值，並在接下來的一段預設時間中，持續觀測電力線訊號的傳輸速率是否仍有大幅度的變化。若電力線訊號的傳輸速率仍持續地減少，即表示此電力線迴路上的電力供應發生異常，則主機裝置20可以透過聲音、影像或是 文字訊息之方式將此異常現象通知給使用者，並自動地或是等待使用者手動地停止供應電力給耦接於此電力線迴路上的全部電器裝置30或是特定電器裝置30，直至此異常現象解除，方回復供電。 According to the above, if a power line communication device is further amplified in the power line circuit, the transmission rate of the power line signal will be decreased. At this time, the host device 20 controls all the power line communication devices in the power line circuit to perform the transmission rate of the power line signal. Test each other and use the above test results to set the threshold value of each power line communication device, and continuously observe whether the transmission rate of the power line signal still has a large change in the next preset time. If the transmission rate of the power line signal is continuously reduced, that is, the power supply on the power line circuit is abnormal, the host device 20 can transmit sound, image, or The manner of the text message notifies the user of the abnormality, and automatically or waits for the user to manually stop supplying power to all the electrical devices 30 or the specific electrical device 30 coupled to the power line circuit until the abnormal phenomenon Release, the party returns to the power supply.
請參照圖3A，圖3A係繪示依據本發明之電力線通訊系統於實際操作時的一示意圖。如圖3A所示，當第一電力線迴路C1中的電力線通訊裝置10a無法透過自身的電力線通訊模組103或無線通訊模組104通訊連接到主機裝置20時，則於第一電力線迴路C1中的其他電力線通訊裝置10b(或10c、10d)可以藉由自身的儲存模組109，據以將指示有電力線通訊裝置10a的資料訊號輸出至主機裝置20。 Please refer to FIG. 3A.

請參照圖3B，圖3B係繪示依據本發明之電力線通訊系統於實際操作時的另一示意圖。如圖3B所示，當第二電力線迴路C2中的電力線通訊裝置10e~10h皆無法通訊連接至主機裝置20時，此時若電力線通訊裝置10e欲傳輸資料訊號至主機裝置20，則電力線通訊裝置10e或是其他在自身的儲存模組109儲存有電力線通訊裝置10e之資料訊號的電力線通訊裝置10f~10h任一者可以透過無線通訊之方式將電力線通訊裝置10e之資料訊號傳輸至第一電力線迴路C1中的任意一個電力線通訊裝置10a~10d，最後再由其中一個的電力線通訊裝置10a~10d間接地將指示有電力線通訊裝置10e的資料訊號輸出至主機裝置20。 Please refer to FIG. 3B. FIG. 3B is another schematic diagram of the power line communication system according to the present invention in actual operation. As shown in FIG. 3B, when the power line communication devices 10e to 10h in the second power line circuit C2 cannot be communicably connected to the host device 20, if the power line communication device 10e wants to transmit the data signal to the host device 20, the power line communication device 10e or any other power line communication device 10f~10h storing the data signal of the power line communication device 10e in its own storage module 109 can transmit the data signal of the power line communication device 10e to the first power line circuit by wireless communication. Any one of the power line communication devices 10a to 10d in C1 is finally indirectly outputted to the host device 20 by the power line communication devices 10a to 10d of one of the power line communication devices 10e to 10d.
換句話說，當第二電力線迴路C2中的電力線通訊裝置10e~10h皆無法通訊連接至主機裝置20時，第一 電力線迴路C1中的電力線通訊裝置10a~10d至少其中之一藉由自身的儲存模組109，據以將指示有第二電力線迴路C2中的每一個電力線通訊裝置10e~10h的資料訊號輸出至主機裝置20。 In other words, when the power line communication devices 10e to 10h in the second power line circuit C2 are not communicably connected to the host device 20, the first At least one of the power line communication devices 10a to 10d in the power line circuit C1 outputs a data signal indicating each of the power line communication devices 10e to 10h in the second power line circuit C2 to the host through its own storage module 109. Device 20.
值得注意的是，本發明之電力線通訊裝置10a~10h皆可以設置有一組查找表(lookup table，LUT)，其用以於相同電力線迴路中的電力線通訊裝置皆儲存有指示特定電力線通訊裝置的資料訊號之情況下，若欲傳送上述的特定電力線通訊裝置的資料訊號時僅需致能其中一個電力線通訊裝置，使得指示特定電力線通訊裝置的資料訊號可以擇一進行傳送。換句話說，藉由在每一個電力線通訊裝置10a~10h設置一組查找表，使得當該些電力線通訊裝置欲傳輸的資料訊號相同時，則僅需選擇其中一個電力線通訊裝置進行傳送，此種群組廣播方式相較於傳統上每一個儲存有指示特定電力線通訊裝置的資料訊號的電力線通訊裝置皆要致能進行傳送，更加的節能以及有效率。 It should be noted that the power line communication devices 10a to 10h of the present invention may be provided with a set of lookup tables (LUTs) for storing data indicating the specific power line communication devices in the power line communication devices in the same power line circuit. In the case of a signal, if only the data signal communication device of the specific power line communication device is to be transmitted, only one of the power line communication devices needs to be enabled, so that the data signal indicating the specific power line communication device can be transmitted alternatively. In other words, by setting a set of lookup tables in each of the power line communication devices 10a to 10h, when the data signals to be transmitted by the power line communication devices are the same, only one of the power line communication devices needs to be selected for transmission. The group broadcast mode is more efficient and efficient than the conventional power line communication device that stores the data signal indicating the specific power line communication device.

Referring to FIG. 3C, FIG. 3C is a schematic diagram showing the power line communication system according to the present invention in actual operation. As shown in FIG. 3C, the smart handheld device 40 can communicatively connect the plurality of power line communication devices 10a-10h to transmit operational commands to the power line communication devices 10a-10h. When the smart handheld device 40 (for example, an iPhone, Android Phone, or Windows Phone) wants to transmit an operation command to one of the power line communication devices 10a to 10h, the power lines of the power line communication devices 10a to 10h themselves are used. The communication module 103 or the wireless communication module 104 transmits an operation command to the designated power line communication device, so that the power line communication device performs the corresponding operation. In other words, the power line communication devices 10a-10h are more communicably connected to the smart handheld device 40, and the smart handheld device 40 can cause the power line communication devices 10a-10h to perform actions corresponding to the operation commands by transmitting operation commands.
